Patent DE-2531799-A1 (DE)
Title: Automatic control for extending flaps on aircraft - operated in conjunction with ram pressure in air sampling tube
Inventor: SCHUSTER WERNER DR
IPC: B64C13/16
Filed: 1975-07-14
Abstract: The aircraft wings are fitted with leading and trailing flaps which are extended to take-off and landing. In order to provide a fail-safe interlock which prevents the aircraft flying at high speeds with flaps extended, the system has an automatic flap control. A control tube monitors the amount of air pressure set up by the ram effect and operates a set of switches in conjunction with the level of pressure. As the pressure increases above a set level the flaps are progressively retracted. The flap control is also linked to the ground speed of the aircraft wheels so that as the aircraft slows to taxi, the flaps can be retracted again. They are extended as the ground speed picks up for take-off.

Yarsn can be wound onto bobbins at constant tension to provide bobbins of uniform yarn density. Pref. the discharge of the yarns from the pneumatic crimping device takes place a speed corresp. to a required yarn quality. Its rate is pref. controlled in response to the speed of yarn supplied to the pneumatic crimping device.

Title: Waste water neutralisation reactor - having inverted cone shape with apex inflow, radial discharge channels and submerged chemical addn. inlet
Inventor: STEUER JOERG DIPL ING
IPC: C02F1/52
Filed: 1975-11-05
Abstract: A reactor tank for neutralization of waste water has the shape of an inverted cone with an angle of 60-80 degrees and with the influent pipe at its apex. Radial outflow channels on the surface lead to a central discharge pipe. The chemicals are introduced through a pipe just below the fluid level. This saves the risk of clogging of pump and influent pipe if the chemical is added to the incoming water flow. The pump requires less power and the whole design is simple.

Title: HV overhead line stringing method - incorporates use of guide pulley with latch and is threaded by crew of helicopter
Inventor: KAEUFL OTTO DIPL ING
IPC: H02G1/04
Filed: 1975-12-20
Abstract: The guide pulley (1) is carried in a block (5,6) which is suspended on one side (6) only from the insulator string (12). The entry to the pulley is closed by a counterbalanced latch (4) whose normal position is closed. A guide (3) for entering the pulling rope (7) is attached to the free end of the block (5) and is about 1 to 1.5 meters long. The threading is carried out by a helicopter crew only. The pulling rope is taken aloft, but with one end on the ground, and trailed towards the transmission tower. The helicopter is positioned such that the rope is caught by the guide (3). A reduction in altitude will then cause the rope to operate the latch (4) whereupon the rope enters the block and becomes captive.

Title: Periodic noise suppression circuit for telecommunication system - uses interrupt switch to break link when motor thyristors noise appears
Inventor: HERRMANN WALTER
IPC: H03G3/34
Filed: 1976-04-28
Abstract: The periodic noise suppression circuit prevents the periodic noise generated by thyristors or triac etc. used to control motors from interfering with the quality of reception in a voice or data telecommunications system. This is achieved by using the noise to open a switch connected into the voice or data path. A first timer (containing a noise-spike integrator) is started by the noise spike and has a period less than that of the noise itself. At the end of this timer's period a second timer is started having a period equal to or larger than the duration of the noise. This second timer operates the interrupt switch.

Title: Frequency multiplexed signal transmission - allows high channel density by relating all signal frequencies to base reference frequency
Inventor: HAASE WERNER DIPL PHYS
IPC: H04B3/46
Filed: 1977-03-29
Abstract: A frequency multiplexer technique is established that permits a high channel density within the speech frequency bandwidth. The frequency signals from a large number of sub stations are transmitted back to the central exchange in relation to a base reference frequency. The substation receives (G) the incoming reference signal that is processed through a bandpass filter (BP). A programmable frequency divider (T) operates on the signal to produce the required frequency for transmission (fn). A phase locked loop (PLL) detects any erroneous condition in the frequency.

Title: Reduction furnace electrode submersion depth control - using computer evaluation of constant mechanical data and measured operation values
Inventor: LACHMANN GEORG
IPC: H05B3/00
Filed: 1977-05-13
Abstract: The system used on reduction furnaces serves for automatic positioning and control of the electrode emmersion depth. The system uses a computer, in which mechanical data relevant to the operating condition of the furnace are stored. The constant value stored in the computer consists of the distance (L1) between the fixed point (a) on the framework of the furnace and a selected point (b) on the furnace pot. The variable measured values are the respective weight (Qges) of the length of electrode and the distance (L2) between fixed point (a) and point (c). The computer creates a difference (Lx) between the constant value (L1) and the sum of the stored values of (L2) and of (Qges). The latter is expressed on the basis of a linear relationship between weight and length of the electrode.

Title: Brake mechanism for a loom warp beam - automatically maintains constant wind-off tension in the warp yarns by controlling tension in brake band from yarn winding dia.
Inventor: DEWISPELAERE ANDRE
IPC: D03D49/08
Filed: 1977-10-13
Abstract: The brake mechanism is provided with an arm mounted in hinged manner relative to the loom frame. A follower element following the outer periphery of the yarn on the beam is mounted on the arm at a distance from the hinge axis. A transmission is provided between this arm and the adjustable end of the brake band. The transmission is so constructed that a rotation of the arm e.g. caused by the redn. of the outer dia. of the yarn windings on the beam, reduces the tensile force on the brake band and hence the braking action on the beam. The mechanism provides a simple and relatively cheap automatic braking system.
